化工装置的防腐,关系到装置效能的发挥,同时也是生产实践中的难点问题。结合本人多年的工作实践,本文试图从生产或设计的工艺过程、制造工艺;检修及维护管理等角度,就如何科学、经济地提升化工生产装置的材料耐腐蚀性进行探讨。 Corrosion of chemical plant, related to the performance of the device, but also the production of difficult problems. Combined with my many years of work practice, this article attempts to explore how to scientifically and economically improve the material corrosion resistance of chemical production units from the perspectives of production and design process, manufacturing process; overhaul and maintenance management.
